Our mastic Joint Adhesive for Blue Sky rubber outdoor tiles is available in a convenient 30 ounce tube. This is a polyurethane based joint sealant. It cures under the influence of atmospheric moisture to form an elastomeric material with adhesive properties, in some cases without the need for priming of the substrate. This formula features strong, early, wet strength to resist slippage on vertical surfaces and is water resistant once fully cured.

Product Questions:

How much of this per sf? Do you glue these tiles to the ground or just to each other?

The manufacturer recommends that each tube can over 10 tiles for the glue down installation, and when used between the tiles, each tube will cover 20 tiles. The tiles should be glued to each other and then the tiles around the 2 perimeter courses should be glued to the ground.
